To all whom it may concern.-

Be it known that I, DAVID W. Bovnn, a citizen of the United States, residing at Wa terloo, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Apparatus for the Construction of Plastic Walls, of which the following is a specification, reference being had therein to the accompanying drawings.

Myinvention relates to improvements in apparatus for the construction of plastic walls.

The object of my invention is to provide means for supportin the mold-sections in the construction of walls, and pertains particularly to means for independently supporting and adjusting. the mold-sections from the outside, so that the said means does not interfere in the filling in between the mold-sections and the backing. By this structure it will be readily seen that the usual means extendin from the backing across themold to the mold-sections is dispensed with, thus 0b.

viating great trouble experienced in removing said means from the completed wall after it has hardened.

Another object of my invention is to provide means whereby the whole frame carrying the separate adjusting means is drawn inward should the pressure of the cement tend to bulge the same outward.

A still further object of my invention is to provide a more simple, cheap, ,and effective means for independently or jointly adjusting the front of the mold-sections from the outside.

In the accompanying drawings, Fi ure 1 is a side elevation of a section of Wall under construction, showing the section-adjusting means. Fig, '2 is a vertical sectional view taken on the line :2 a: of Fig. 1. Fig. 3 is .an enlarged perspective viewof the framework on the outside of the mold-sections for holding the same. Fig. 4 is an enlarged perspective view of the joint between the mold-sections.

Referring now to the drawings, 1 represents a backing for the concrete wall, which, as. shown, is preferably constructed of vertically-disposed timbers 2, having their inner faces covered bytwo-inch lankings 3, laced close together to form a so id backing or the .wall. The said backing is held in a vertical position in any desired manner. Usually in constructing walls of this character the moldsections are held to the backing by meansof bolts or the like passing across the space between the backing and the mold-sections, so that these bolts interfere with the filling in of the cement and also are left within the wall and removed after the mold-sections are removed, which in many cases is difficult and which is also objectionable because it leaves openings in the wall. In my invention, as before stated, the usual backing is used, and I provide a framework adjacent thereto, and said framework is composed of vertically-arranged timbers 4, which have secured thereto at predetermined distances horizontally-arranged cross-bars 5, which, as shown, are on the inside-of the vertical timbers. The said horizontally-arranged bars are provided throughout their entire length with the horizontally-arranged slots 6. Between the said framework and the backing are arranged the mold-sections 7, which, as is understood, are usually of the same Width in constructing a building, and thus the joints between the upper and lower edges of the mold-sections are always the same distance apart. Thus the ranged the'same stance apart on the upright 4, so that the slots 6 are at all times opposite the joint between the u per and lower faces of the mold-sections, the purpose of which I will now proceed to describe.

The mold-sections, as shown, are of different lengths, and this is necessary in building between windows or ending u a wall at thecorner, as illustrated at the feft of F i 1. Should the regular length section be toolon to fill the space, a shorter section is used, and thus sections of all lengths are necessary. The corners of each mold-section are cut away at 8, and passing through the opening formed by the two cut-away portions of the abutting corners, of the sections are bolts 9, which have their heads 10 abutting the inner faces of the mold-sections. The said bolts are screw-threaded throughout their entire len th, and each bolt on the outside of the mo d-sections is provided with a nut 11, by means of which the mold-sections are clamped between the sam and the head of the bolt for holdin the sections together. The said bolts extend outward through the slot 6 in the horizontal bar 5, and on the inside thereof are provided with nuts 12 and on the outside by nuts 13. The said bars 5, as shown, are a dis tance from the moldsections, and by the adjustmentof the nuts 12 and 13 the mold-sec- .itio ns are adjusted in or out, as desired, to

all of them in a vertical alinement.

with theopenings 1. 1, so that the adjusting the members 5, it

' The bolts 9 passin through the slots 6 in beseen that the bolts may be arranged in or at any point along the same that aijoint between the mold-sections occurs, and thus when using the smaller mold-sections the bolts are easily usedor ad justed. The standards 4 opposite each of the slots-6. of the horizontal bars are provided bolts 9 me pass therethrou 1. when thejoint of themold-sections comes directlyunder the said standard. In such acase it is understood that a longerbol-tisused, buttheopera tion is precisely the same.

The mold-sections, as shown Fi 4, are provided on two. sides with the over apping flange 15', which'extends over the two abutting sides. of the adjoining sections which are not provided" with the flanges, and thusthe 1 joints between the sections areclosed by the flange and-the cement is: prevented from passing between the same.

In using moldnsections of this character the pressure ofthe'cement placed between the backing and themold-sections moves the framing slightly out of alinement, and in order to prevent this andalso. to strai htenrthe said framework, should such. occur, provide transverse tie rods or wires 16, which pass through the planking and uprights; of the backing and are secured thereto inany (is sired manner. The said. tie rods or wires pass acrossv the s ace 17 to be filled with cementand throng the elongated slot 6 of the cross-bar 5 and through one of the openings 14 in the standard 4.. The said standard is provided with a U-shaped truss-plate 18, which is rigidl secured thereto and provided with a hooke bolt 19 passing therethrough and provided at its inner end with the hook 20, which engages a loop 21 in the tie rodor wire 16. Said bolt on the outside of the truss-plate 18 is provided with a nut which by turnin draws the bolt 19 outward and tightens t e tie rod or wire 16. It will-be seen that these bolts or wires are arran ed at the top and bottom'of the frame, ands ould the pressure of the cement tend to force the mold-sections and the framework outward the tie-rods are tightened, holding the sections in their proper position. It is also understood that the mold-sections are removed after the cement is hard, and the framework is alsomovedupward, while the tie-rods are left in the wall and cut. off, and,-'as before stated, the horizontal bars when-raised are always in an alinement with. the abutting horizontal edge of the mold-sections.

Having thusdescribed my invention, what I claim, and desire to secure by Letters Patcut, is-
